That's a good idea, I need to get small stands for them. They are actually Polk bookshelf speakers that I got on Amazon for $50 (pair), they sound really good. I had Presonus e4.5's in their place before; they sounded OK but didn't quite get the volume I wanted.

Only thing I can recommend is make sure your TV is in computer/gaming mode as that'll typically lower the latency of the response time. TVs typically have much higher response times than computer monitors so using them in scenarios where lower latency matters, you have to make adjustments.
